When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- A dripping waste or valve behind a panel
- Mould caused by poor ventilation, which will return until the extract is fixed
- Loose panels, vanity units or tiles, which need fixing first
If you are not sure, just phone 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Washroom sealing for commercial buildings in Northaw
When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. If you have resealing that didn’t last because the old bead stayed and failed joints along IPS and cubicle panels, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Northaw tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Halls and community buildings near places like Northaw are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Leave it or put it right?
Water gets behind panels and under floors through a failed joint. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours, and fixing that takes far more work than resealing. For buildings around smaller places like Northaw, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
A quote for washrooms and wet areas depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

How a job runs
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and our waste is bagged and taken away as we go.

- Leaks, loose panels or damp are pointed out first.

Advice
When to call us in Northaw
Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed, and shower trays shift under foot. A bead that can’t cope with the movement splits along one edge.
Site and facilities staff are often the first to spot these:
- Mould spotting along silicone joints
- Stained or open joints at kitchen sinks and worktops
- Gaps where vanity tops meet the wall
- Users noticing mouldy joints
For a campus such as University of Hertfordshire, which lies north of Northaw, showers in residences and washrooms in teaching blocks can be programmed around term dates.
What your quote should include
- The terms of the workmanship guarantee
- Is the sealant right for the movement and the substrate?
- What site paperwork they can supply
- Can the work be phased to keep areas open?
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Questions about Northaw
Is a smaller place like Northaw outside your area?
No. Places such as Northaw are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work around term dates at a campus such as University of Hertfordshire?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
How long before the toilets can reopen?
Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so facilities are never short.
Can you reseal washrooms in healthcare buildings?
We work in clinics, hospitals and care homes. Tell us what records you need and we’ll confirm with the quote before we start.
Do you offer coloured sealant?
It depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Work for main contractors and building owners
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Northaw. Several sites can go on one quote, which keeps the paperwork simple.
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
